Comments: Large, fast growing species. Most important in the markets of the Chao Phraya and Mekong in Thailand. Might be valuable in mixed culture with P. hypophthalmus in ponds populated by molluscs (Ref. 7432). Migrates upstream from March to August from the Khong Island, just upstream Khone Falls in Laos to Chiang Saen in Thailand (Ref. 37770). Juveniles of 4 cm appear at Klong Kaem District, Ubolratchatani Province and at That Phanom District, Nakhon Phanom Province (Ref. 37770). Museum: Mekong river at Bung Kla, 140 km nw of Nakhon Phanom, CAS 67216 (Ref. 5515). Also Ref. 26336, 37770, 41485.

Short description Chiavi di identificazione | Morfologia | Morfometria

Raggi anali molli: 25 - 30. Dorsum dull grey with pale green iridescence; maxillary band of teeth forms a continuous row with no break in midline (Ref. 12693). Snout protruding with upper jaw tooth bands partly exposed when mouth is closed; large median vomerine tooth plate (Ref. 43281).

Facultative air-breathing (Ref. 126274); Occurs in large rivers (Ref. 12693) and enters flooded forests (Ref. 9497). Found in rapids and in deep slow reaches (Ref. 37771). Juveniles feed on prawns and insects; subadults and adults on prawns, insects and particularly mollusks which are more predominant in stomach contents than in any other Pangasius species (Ref. 7432) and on plants (Ref. 9497). Migrates into the middle Mekong along the Thai-Lao border as water levels and turbidity begin to increase. Reproduces early in the flood season and juveniles of 6 to 7 cm are taken by late June (Ref. 12693). Marketed fresh (Ref. 12693).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00221 - 0.00684), b=3.13 (2.97 - 3.29), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 2.7 ±0.34 se; based on food items.

Resilienza (Ref. 120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Preliminary K and tmax; Fec=18,000-42,000).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (88 of 100).

Price category (Ref. 80766): Unknown.
